SPECFICATION ormfing'guart Letters Patent No. 307,273 dated October 28, 18H4.

Appncanonniea Febmaij 2s, nasi, No mmm.)

Be it known that i, JOSEPH DUVAL, of the Village of Laprairie, in the county,T of Laprairie and Province of Quebec, Dominion of Canada,

have invented certain new and useful Ini` provements in Breech -Loading Fire'- Arms; and I do hereby declare that the following is a full, ciear, vand. exact descriptionof the saine.

This invention relates to imorovemcns in ro hreech-ioading revarrn's; and its object is to furnish gun which will be simple Ain construct-ion and cheap'to manufacture, in which the nuniher of parts sha1-line reduced to a minimum, in which the operative mechanismmay be readily removed when necessary, and which can he loaded and i'ired with great rapidity.

The invention consists, partly, in an ini proved construction and arrangement or" the 2o loading, cooking, and firing devices; fur-ther,

in the manner of securing the operative mech` anisni in the gun and locking it in a peculiar manner, so that it may he insiantly reinoVed; and, 'urti'ier, in various delails of construction,

'and in the novel combinations of the parts, all

fully hereinafter explained. Y

In the drawings, Figure l is a side elevation; E, a detail of the camend key for removably securing the operative parts within the chamber. Fig. 3 is :i longitudinal vertical section. Fig. e is n partial side elevation, the gun having just been fired. Fig. 5 is en end View of Fig. 4,. Fig, 6 is a View similar to' Fig. with the position for reloading. L Fig. Z is a. section on line a" .o of Fig. 3. Fig.

8 is a section on line y y of 3.

A represents the stock, B the side walls of the slot-ted chamber, C the tang embedded. in the stock, und D the barrel, yli of the nsual construction.

The borrel-) screwed to a suitable lug, so that it may he removed in order that rifled and smooth-bore barrels may he used interchangcalily. Y K

E isltlio cnririfflgc-chamber, in line with the bore oi' thc haricl.

F is an extension of the stockwhioh supports and. partly incloses. the barrel, l. nativo zi'icclninisin is supported by a frame, W, Fins. d. and o. This frame is coniposcd of a Versioni Standard, W", and a slotted bascplate, W2. The standard W has two shoulders, 'w w, which enter rabhets in the metal plato C', snc-h plate being rigidly conneccd to thc stock hy the tang C; The standard there fits closcl y and bears irmly against the plate C atthe rear. The breech-blockl G closes the slot in the chamber, and is pivoted upon a pin, K, in the standard W. It extends forward tothe cartridge-chamber, and 6o has a cartridge-groove. g, upon its upper surface, and a horizontal perforation, g', through which the firing-pin projects. At its rear is a downward projection, g', the object of which v will be hereinafter explained. The hammer I is pivotcd upon a pin, M, in the base-plate W2,

a roundedhinge-joint being formed, as shown in Fig. 3. The blockfspring Nfw-hielrrprojcets the hammer forward, is of au invertedef' shape, and its free end bears upon a projection, l', 7@ on the 'rear of the hammer. The latter is also provi led with the ordinaryhalf and fnlleock notches, Fig. 3.` The firing-pin H is pivot-ed at the upper extremity of the hammer, and projects forward through a perforation in 7 5 the broechhiock. rihe trigger P is pivoted upon a transverse pin in the base-plate, and has projecting spurs p' p2, which engage with either or" the notches in the hammer. The trigger-spring p is of ordinary oonstrnctiomo and is held by a sorevnQ. The extractor Q -is a helbcr'anlr lever pivoted in the base-plate W2, and having armsT T2. One arm of the lever extends backward, Fig. 6, in position to be struck by the descendingy breech-block. 8 5 The extracting-arm projects upward and engages with the rim of the cartridge.

E is a safety-key which slides in a space hetween the stock and triggerlgnard, and is provided with a handle, S', and a light spring, S", go Fig. 3. The end-of the key is slipped below the end p2 of the trigger, oloviatingv all danger of accidental discharge.

J represents the lever -pvoted on the pin M, which supports the hammer. The lever ex- 954 tends down through the slot in the baseplate to a point below the stock,l where it may be easily reached by the hand. It also extends up above the pivot, its upper end being formed.y with a projection, which enters a notch e in the Ioo breech-block when the `latter is elevated. AWirren the lever 'is thrown down, its rear portion strikes a pin,v fi, ou the hammer and throws the latter back to -half or full'coek. It Will'be .readily understood froml Ithis that the lever and hammer, beiugpivoted upon a common pin', move backward arene, but may move., forward independently, described hereinafter.

as will belmore fully Theoperation ofthe parts thus far described is as follows:v snpposingthe guntoghaveju'st 4been iired, Fig. '11,.the' lever J is irst thrown down, throwing backthe hammer and strikbreech block falls, bringing the cartridge-l groove in linepwith the chamber E. In its de-l ing the projection giof the breech-block. The

scentv it strikes the extractor, which throws out the exploded shell. A cartridge is placed lin grooveof the breechblock andv readily pushed into the. chamber.

rfullrcock, it is now ready to be discharged.

When the'trigger is pulled, the hammer is thrown forward independently, driving the pvoted ringpin against theprimer of thel cartridge.

In Figs. 2, 3, and 7 is illustrated a device for locking the frameW within the breech, and

permittingit, with the breech-block, hammer. lever, trigger, and extractor, .to be removed at once and by a single movement. A cavity, F,is formed inthe part F of the stock, in which is a strong pressure-springfUa. This spring bears on the end of a double sliding key, U2@

the arms of which enter slots U U. the slot U. being in' the end of the frame W, while the inner face of the key bears against the end of said.l frame and forces it back. Be-

tween the arms of the key is pivoted upon a transverse bolt a cam, U, which has a projecting thumb-piece or handle, U", Fig. 1. By means of this handle the camA is forced against the key crowding it into the cavityin the stock, and withdrawing the sliding arms from engagement with the slots U U. By a slight'forward movement of the lever .I the frame W is dibsengaged from the plate C. If the lever is then forcibly pulled down, the entire frame and'fall the parts'pivoted therein maybe withdrawn from the breech, either for purposes of cleaning or repair or to render the gun useless in case of necessity.

- Having thus described my invention, what I claim is.- A

1. In a breech-loading gun, the combination, with the chambered stock, of a supporting-frame, W, having the breech-block, hammer, lever, and extractor pivoted therein, and

a sliding key, U, working in the recess F of the-stock for locking such frame, constructed and operated substantially as described. 2. The combination, with-the stock, of the,

removable frame W', carrying the lock mechanism, the-key U, sliding within the recess F oi' the stock for securing the frame, andthe spring U3, substantially as described. y I' 8. The combination. with the, chambered stock, of the plate C', the removable franIeW, supportingt-helock mechanism and composed of a ,base-plateand standard, the key sliding within the recessF, and the cam -for operating the same, all substantially as described.

4. In combination with the chambered stock having the recess F, and withthe lock-bear- 'ing frame W, thedouble sliding. key, the pivoted cam having'the handle U, and' the spring'y U3,'subs`ta ntially as described.
